A research expedition to Antarctica to study the region’s octopus life has returned with descriptions of four new species, and the first known sub-zero venoms.

“Antarctic octopus venom works at temperatures that would stop other venoms in their tracks,” said biochemist Bryan Fry of the University of Melbourne, who led the expedition.

Antarctic octopuses eat a wide variety of animals, from clams to fish. They catch their prey with their tentacles and use their venom to kill them, much like snakes.

The venoms are being studied as potential sources of pain-killers, Fry said, because they work on the nervous system. So far, analysis of the venom has revealed two toxins that are new to science.

The scientists still don’t know what biochemical tricks the octopuses use to keep their venom working at freezing temperatures.

Every time I see or read an article on new cephalopod life, I'm always intrigued. Is there anything they can't do? We will one day be ruled over by the Octopi.

Am I the only one who thought the octopus could shoot venom at its prey, which would then be flash-frozen?

Cool nonetheless though.

Raccoons and cephalopods, man.

T-Rex is right to be worried.
